HYDRAULIC MOTOR.

Specification of Letters Patent.

Patented July 9, 31912.

Application filed August 22, 1910. Serial No. 578,320.

Be itknown that I, Ronnn'r S. CARR. a citizen of the United States, residing at- ()xford, ()hio, have invented a new and useful Improvement in Hydraulic Motors, of which the following is a specification.

My invention relates to hydraulic motors of the class adapted for operating washing machines or wringers or for other suitable purposes, and the objects of my improvements are to journal the piston in bearings formed in the casing and independently of the main shaft for preventing it-from binding in its bearings; to provide means for utilizing the water pressure for unseating and shifting the discharge valve; to provide automatic clutch and gear mechanism for translating alternating into direct rotative motion; to provide means for moving the motor with the main shaft into dif fercnt vertical angles to automatically engaging and disengaging the clutch and gear mechanism and also for detachably engaging a shaft journaled in a fixed position; to provide a fixed stop for detachably engaging with and preventing the crawling of the secondary shaft when out of action; to provide automatic means for disengaging a splined cover for the main shaft; from being rotated thereby, and to provide simple and durable construction and assemblage of the various members for securing facility of operation and etlicicncy of action. 'lhese objects are attained in the following described manne' as illustrated in the accompanying drawings, in which:--

Figure 1 is a vertical diametrical section of a hydraulic motor embodying my improvements: Fig. 2 a plan with parts broken away; Fig. 3 a vertical section on the axis of the valves; Fig. -l a diagram in section of the ball clutches: Fig. a vertical section of the hinged member for moving and maintaining the motor with the main shaft in different vertical angles. Fig. (5 a horizontal section of the toggle joint connections with the wringer shaft. and Fig. 7 a section on the line 6-4) of Fig. 1.

In the drawings, 1 represents the tub of a washing machine, 2 a metal coverthereon formed with a wringer bracket 3 whereon a wringer with its shaft 4 may be removably secured. A lid 5 removabl 'v hinged on the cover may be maintained in a predetermined vertical angle by the'contact of the projecting leg 6 thereon with the cover. A 1 bed plate 7 secured on lid 5 is formed with j an axial'bearing 8 and with a lateral hearing 9. The motor removably secured on said bed plate consists of similar top and bottom members 11 and 12 removably secured together in the ordinary manner and formed with respective inlet and discharge passages 13 and 14. Each of said members is also formed with an axial bearing 15 and with an annular packing groove 16 concentric therewith.

A piston 17 journaled in bearings'15 is formed on its ends with annular thin projections 18 adapted to be compressed partially within the packing in grooves 16 for reventing leakage. Said piston is also formed with arms 19 adapted to project radially within the annular cylinder 20 which is preferably circular in cross section. The main shaft 21 formed with a collar 22 may be journaled in bearing 8 and splined cylindrical housing 24 is formed with a tangential slot 25 adjacent to the piston for the reception of the packing 26 and also formed with projecting lugs 27 adapted to detachably engage with reee ses 28 formed on the inside of the members of the casing, whereby said housing may be removably setight partition across the cylinder 20. Said housing is provided with the usual balanced discharge valve 29 and also with the balanced inlet valve 31 which is for..ted with extensions 32 of the ends of its stem.

("up packings 33 may be secured on the respective arms 19 of the piston by means of the clamping plates 3-1 and screws 35. Said plates are each formed with a boss 36 for unseatii'ig the inlet valve-by contacting with the corresponding extension 32 of the in bearings 38 on opposite sides of the housing 24 with one endterminating in engagement with the corresponding end of the discharge valve 29. The other end of said levers terminate in cup shaped closures 39 formed with slots 41 for the movement therethrough of the extensions 32 of the stems of the inlet valve. Said closures may bev actuated in one direction by the movement of the discharge valve to alternately in an axial slot 23 formed in the piston. A

cured within the casing to form a water,

stem thereof. Levers 37 may be trunnioned cover the stems of the inlet valve and obstruct the corresponding inlet port thereof. The discharge of the water under pressure through the inlet port after the inlet valve is unseated therefrom serves to actuate the corresponding closure to uncover said port and also to unseatandshift the discharge valve.

A tubular member 42 provided with a dolly 43 serves to cover the lower portion of the main shaft and prevent it from injuring the clothes in the tub. Said member is formed with interior longitudinal grooves 4-1 whereby it is splincd on the main shaft by means of the transverse pin 15 therein. Said grooves terminate in a chamber 46 formed within the lower end of said member for the movement therein of said pin after it is disengaged from the grooves by the movement of the dolly into contact with the bed plate. A transverse pin 47 in the upper portion of member 42 serves to intercept one end of pin 45 to prevent the removal of said member from the main shaft.

A secoi'idary shaft 48 journaled on the bed plate in bearing 9 is provided on one end with pinion 4:9 and on the other end with a pinion 5l which is .adaptedto engage with a fixed stop on the cover when the lid is closedfor preventing said shaft froi'n turir ing. \Vhen. the lid is opened as shown in Fig. said pinion engages with gear 53 which is secured on a hollow spindle 50 whereby it journaled in bracket 54. A StK'liQt provided with a set screw 56 for securing the wringer shaft 4 therein is con-' nected with the spindle 50 by means of the toggle pin 58 in such manner that the \\"ringer shaft may be rotated thereby whenout of alinen'ient with the axis of gear .33.

Idle gears 59 and 61 are idly mounted on the main shaft between the collars 22 and (i2 and in continuous engagement with the pinion 49 on shaft 48. A sleeve 63 secured on the main shaft between said idle gears thereon is formed on one end with a series of inclimdv lugs (i l to project within the annular channel (35 formed in the adjacent end of gear 50. A series of similar inclined lugs or teeth (56 formed on one end of gear (El project within .the similar annular channel (3? fori'ned in the adjacent end of said sleeve. Gravity metal balls (38 are disposed within said am nlar channels and between the adjacent said lugs therein, as shown in l lf'jfi. l and =1.

In operation, 'atcr admitted under pressure through one of the inlet portsto the interior of the cylinder serves to turn the piston and unseat the inlet valve from the opposite inlet port by contact with the corrcspondii'ig extension of its stem. The water thus admitted under the valve through the inlet. ort just opened forces the lever with the cm'r(. s )onding closure to uncover said port and simultaneously unseat and shift the discharge valve. This movement of the discharge valve moves the other lever with its closure to shut the former inlet port. During the almost instantaneous shifting of the discharge alve the reversal of the direction of the water toward the now opened discharge port acts as a 'ater hammer for completing the shifting of the unseate'd inlet valve. This action of the valves admits the water to the interior of the cylinder on the opposite side of the housing for turning the vertical angle and with the pinion 51 inengagement with gear 53, one or more of the gravity balls in one of the channels. engages the corresptmding idle gear to turn with the shaft in one direction and when the shaft is turned in the opposite direction said idle gear is disengaged and the other idle gear thereon is engaged by one or more of the balls in the other channel to turn with the shaft whereby continuous rotary motion may be imparted through the gears to the secondary shaft and thence to the wringer shaft.

\Vith the lid in the open position as shown in. Fig. 5 the vertical angle of the main shaft permits the splined member thereon to slide by gravity toward the bed plate with the pin 45 disengaged from the'grooves 44- and. free htO turn in the cl'nu'nber 46. .Yhen the lid is closed said member by gravity becomes reengaged to turn with the main shaft and the engagement of pinion 51 with the stop 52 locks the secondary shaft from creeping and the balls resume their normal positions with the idle gears remaining unmoved by the rotative movement of the main shaft.
